Align docker load and podman load output

The comma-separated podman load output isn't conducive for using the
subsequent images. For tarballs with multiple images, the comma
separator must be manually identified and a suitable range identified.

Docker CLI on the other hand, has one image identifier per line:

Loaded image: repo1/name1:latest
Loaded image: repo1/name1:tag1
Loaded image: repo2/name2:tag1

(as of Docker version 20.10.16, build aa7e414).

Switch `podman load` to this format for consistency and usability.

[NO NEW TESTS NEEDED]
